Grading, soil, drainage, and site prep, none of it glamorous, all of it the reason your patio doesn't flood, your driveway doesn't wash out, and your yard actually drains where it's supposed to.

Water goes where the grade tells it to go. If your yard slopes toward the house, or your driveway pools every spring, that's a grading problem, and it's usually fixable without tearing everything out. This is also where every other project starts: nothing above ground lasts if the ground underneath it wasn't prepped right.
